Welcome to Sound Deadening
Hi there! My name is Eduardo, I'm a car enthusiast from Portugal who loves silence. In this website you can check my sound deadening projects with pictures, videos, how-tos and some product reviews. Enjoy!
Current project: Opel Ampera
Rear hatch door
The rear hatch on the Ampera / Volt doesn't have much space for deadening. Still I tried to reduce noise from the rain and block heat from the summer sun.
